Believe it or not, I can’t find the answer to this simple question. Could be I can’t figure out the correct search string.

What are rules for legal variables names?  
ie: A-Za-z0-9, hyphen, underscore, etc. must start with an alpha at least n characters, no longer than n characters, etc.

Thanks for the help!
